摘　　要：网络架构的选择与5G网络的部署效率及用户体验密切相关。基于此,分析NSA和SA这两种常见网络架构的特征,并细化探讨了在NSA和SA共存网络架构能力下开展5G平滑演进的必要性。从网络运维优化和网络结构两方面分析NSA与SA共存组网面临的困境,最后探讨了在NSA与SA共存网络架构能力下的可行性5G平滑演进方案,以期为后续的5G网络建设工作提供良好参照。The choice of network architecture is closely related to the deployment efficiency and user experience of the 5G network.Based on this,this study mainly analyzes the characteristics of the two common network architectures of NSA and SA,and discusses the necessity of smooth evolution of 5G under the coexistence of NSA and SA network architecture capabilities.From network operation and maintenance optimization,network structure in two aspects,it analyzes the difficulties faced by the NSA and SA coexistence networking,finally discusses the feasible 5G smooth evolution scheme under the coexistence network capability of NSA and SA,in order to provide a good reference for subsequent 5G network construction work.
